THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 627,426, dated June 20, 1899.

Application filed July 12, 1898. Renewed May 15,1899. Serial No- 7l6,919. (No model.)

To all whom it may concern.-

Be it known that I, SYLvEsTER W. KELOH- NER, a citizen of the United States, residing at Fowlerville, in the county of Columbia and State of Pennsylvania, have inventedv certain new and useful Improvements in Antirattle Thin-Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to antirattling thill-couplings; and it consists in the novel construction and arrangement of the parts, as hereinafter described.

The object of the invention is to provide the thill-coupling with a spring of especial construction, said spring being durable in its nature and adapted to prevent the coupling members from rattling. I

The further object of the invention is to provide a pin adapted to connect the shaft with the thill, said pin being of such construction as to avoid the necessity of using nuts or taps to hold it in its proper position.

In the accompanying drawings, Figure 1 is a top plan View of the thill-coupling complete. Fig. 2 is a transverse sectional view of the thill-coupling. Fig. 3 is a top plan View of the spring, and Fig. 4 is a perspective View of the pin.

The ordinary clip 1, having the extending brackets 2 2, is secured in the ordinary manner upon the axle 3. The lower portion of the said clip 1 is provided with the downwardly-extending externally-threaded projections 4, and the perforated plate 5 receives in its perforations the said projections, as shown in detail in Fig 2. The internallythreaded taps or nuts 6 are then secured on thelower ends of the projections t. The plate 5 is thus held in its proper position, and the clip 1 is firmly clamped upon the axle 3. The rear end of the plate 5 is provided with the upwardly-extending flange 7, the object of which will be hereinafter explained. The end of the shaft or pole is provided with the ordinary iron 8, said iron having at its end the ordinary eye 9. The eye 9 of the iron 8 is adapted to pass between the brackets 2 2 of the clip 1, and the pin proper, 10, of the securing-pin 11 passes through the registering perforations of the brackets 2 2 and the opening in the eye. 9. At'on'e end of the pin proper,10, of the pin 11 a rearwardly-extending arm 12 is formed, and said arm is provided at its rear end with an arm 13, which extends in parallel relation to the pin proper, l0. Thearn113isprovided withtheupwardlyextending rigid flange 14, said flange 11 being adapted to pass between the brackets 2 2 of the clip 1, as shown in Figs. 1 and 2, and thus it will be observed that while the flange let is between the brackets 2 2 the pin 11 cannot move longitudinally, and thus it is not necessary to provide taps or nuts to secure said pin in place. The spring 15 is made of a single piece of wire and is provided with the central portion 16, said portion 16 being in a horizontal plane when the springis placed in proper positionuponthecoupling. Adjacentthecentral portion 16 the wire constituting the spring is bent back, forming the parallel sections 17 17, merginginto the upwardly and forwardly extending sectionslS 18,the wire then being bent back and having the downwardly-extending sections 19 19. The sections 19 19 merge into the coils 20 20, said coils being wound about the outer ends of the sections 16 and 17 17. The outer ends of the coils 20 merge into the sections 21 21, said sections extending to the rear and merging into the downwardly-extending sections 22 22. The extreme ends of the wire are then extended in horizontal planes and are secured together by means of a collar 23, or any other suitable method or means for attaching the ends of the wire may be employed. A wire 2a, constituting a link, is secured at its ends upon the rearwardly-extending sections 21 21. The said link is adapted to pass up over the upwardly extending flange 7 of the plate 5 and is adapted to rest between said flange and the rear portion of the clip 1, as shown in Figs. 1 and 2. The sections 18 and 19 of the spring 15 are adapted to pass up behind the eye 9 of the'iron 8 and bear forcibly against the said eye, and thus the coupling is prevented from rattling. At the same time the sections 18 18 pass under the arm 13 of the pin 11, and thus the said pin is prevented from revolving, it being obvious that the flange 14 of the securing-pin 11 is held against the clip 1, which prevents upward movement of said flange, and by reason of the sections 18 18 passing under the arm 13 of said pin and contacting therewith it is also evident that downward movement of said pin is likewise prevented.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A thill-coupling, comprising a clip having brackets, an eye fitting between said brackets, a securing-pin for retaining said eye within the brackets, said pin comprising a pin proper, a rearwardly-extending arm formed at one end thereof, and an arm located at the end of said rearwardly-extending arm and lying in parallel relation to the pin proper, said arm being provided with an upwardly-extending rigid flange fitting between the brackets of the clip, and means for holding said flange in said position to prevent displacement of the securing-pin.

2. In a thill-coupling consisting of a clip and an eye pivotally mounted thereon, a spring adapted to prevent the eye from rattling, said spring consisting of a single piece of wire, said wire having at its middle a horizontal section,said horizontal section merging into two inwardly-extending parallel sections, the last said sections merging into upwardly and outwardly extending sections adapted to bear against the eye, the last said sections merging into rearwardly-extending sections, said rearwardly-extending sections merging into coils, said coils passing around the outer ends of the central section and the parallel sections said coils merging into second rearwardly-extending sections, and a suitable means for securing the said second rearwardlyextending sections to a stationary part.

3. In a thill-coupling, consisting of a clip and an eye pivotally mounted thereon, a spring adapted to prevent the eye from rattling,said spring consisting of asingle piece of wire, said wire having at its middle a horizontal section, said horizontal section merging into inwardly-extendin g parallel sections, the last said sections merging into upwardly and outwardly extending sections adapted to bear against the eye, the last said sections merging into rearwardly-extending sections, said rearwardly-extending sections merging into coils, said coils passing around the outer ends of the horizontal section and the parallel sections, said coils merging into second rearwardly-extending sections, a suitable means for securing the said second rearwardly-extending sections to a stationary part, and a securing-pin for retaining the eye on the clip, said pin comprising a pin proper having formed at one of its ends a rearwardly-extending arm having at its rear end an arm lying in parallel relation to the pin proper, said arm being provided with an upwardlyextending flange which bears against the clip, the upwardly and outwardly extending 'sections of the spring lying under said flange and retaining the same in the position mention ed, whereby the securing-pin is prevented from being displaced.

In testimony whereof I afiix my signature in presence of two witnesses.
